A numerical computation test shows the possibility of inferring the principalaxesof tectonic stress from the p, b, t axis of earthquakes with randomly oriented fault planes.
通过数值试验论证了利用多个断层面随机取向的地震的P、B、t轴推断构造应力主轴方向的可能性。
2
The axesofprincipalstress rotated before earthquake.
震前主应力轴的旋转。
3
The pore water pressure under positive rotation ofprincipalstressaxes is smaller than that under inverse rotation.
